SPECIFICATION forming part of Letters PatentNo. 280,254, dated June 26, 1883.

Application led January 8, 1883. (No model.)

To all whom it may concern: Be it known that I, DAVID E. SoUTIIwIcK, of Ogdensburg, in the county'of St. Lawrence and State of New York, have invented cer- 5 tain new and useful Improvements in Car- Couplings; and I do hereby declare that the fol- 4 lowingv is a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication, and in which- Figure l is a perspective view of part of the end of a railway-car provided with my improved coupling. Fig. 2 is a longitudinal vertical section of the draw-head and link. Fig. 3 is a bottom view of the draw-head, and Fig. 4 is a perspective view of the link.

Similar letters of .reference indicate correspending parts in all the iigures.`

My invention has relation to automatic carcouplings; and it consists in the improved construction of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letterA indicates the draw-head, which is fixed upon a draw-bar of the usual construction. The draw-head is of the usual construction, but has a central recess, B, in which slides a recessed head, C, having a stem, D, and bearing with its inner end against a spiral spring, E, wrapped around the stem. The lower wall of the ilaring draw-head is provided with a bearing, F, in which slidesthe outer wide end of a slotted plate, G, the outer edge of which is bent down, forming a lip, H. The inner end of plate G forms a stem, I, around which is placed a spiral spring, J, bearingw'ith one end against the wider part of plate G, and with the other end against a bearing, K, in which stem I slides.

L is the coupling-pin, whichpasses through holes in the upper and lower side of the drawhead and through the slot in plate G. The

round head M of this bolt is held fastfby a box, N, having a slot, O, in its under side, and an inclined top, so that the head of the bolt may slide forward and backward, according to the draft exercised upon it, while the inclined top will guide it directly vertical when it is dropped. This head is fastened upon an arm,

P, fastened to a rod, Q, which slides in bearings upon the end of the car, and is provided with a handle at its upper end, so that it may be operated from the top of the car. The rod Q, and consequently the coupling-pin, may also be raised from -the side of the car, either by a lever, R, pivoted upon the end of thecar and bearing with one end under a cross-plate,

while at the same time plate G will, by being provided with spring J, allow thelink to move upward, downward, or sidewise while the train is running. The lower end of the couplingpin will rest upon the top of the recessed head C, and when the link enters the draw-head, pushing the head back, the pin will fall, while the spring E will push the head C forward when the pin is raised. For further security the link may be fastened to the car by a chain, X, fastened to the arch W and to the car.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States* l. The combination ofthe draw-head A, having central recess, B, and bearings F and K, recessed head C, having stem D and spring E, slotted plate G, having down-turned lip H, stem I, and spring J, and coupling-pin L, substantially as and for the purpose shown and set forth.

2. The combination ofthe draw-head A, ha'ving spring-bolt C D, couplingpin L, having head M, and rod Q, havingplate S, and arm P, provided with boX N, having slotted under side and inclined top, and means for opA erating it, substantially as. shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

DAVID E. SOUTHWICK. Witnesses:

A. N. PARTRIDGE, JOHN F. CADY.
